Therapeutic blend from Florentine family finally unveiled (9)
I believe the answer is:
medicinal
'therapeutic' is the definition.
(I've seen this before)
'family finally unveiled' is the wordplay.
'family' becomes 'medici' (I have seen 'Italian family' mean 'medici' so perhaps 'family' could also mean 'medici').
'unveiled' says to take the centre (the word's outer letters are taken off).
The middle of 'finally' is 'nal'.
'medici'+'nal'='MEDICINAL'
'blend from florentine' is the link.
This may not be correct. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for medicinal that I've seen before include "With therapeutic properties" , "Good for you!" , "concerning drugs" , "Lily 15's invention" , "of a health-giving nature?" .)
